Description

NF36 Nickel Content 50-55 PTC Ni-Fe Alloy Wire Rod For Electric Heating Blanket,Resistance 0.36

The product exhibits a resistivity of 0.36 at a temperature of 20°C, with a tolerance range of ±0.02.

PTC Ni-Fe alloys NF36 with nickel content ranging from 50% to 55% are specialized nickel-iron alloys known for their positive temperature coefficient (PTC) properties. As temperature increases, the electrical resistance of these alloys also rises, making them highly effective for applications that require temperature-sensitive behavior and self-regulating thermal management. With a moderate level of electrical resistivity, these alloys provide reliable, stable performance across a broad temperature range.

The PTC Ni-Fe alloys NF36 are widely used in temperature sensors, thermistors, and self-regulating heating elements, where their ability to respond predictably to temperature changes is crucial. The alloys’ resistance to oxidation and corrosion enhances their durability, allowing them to perform well in challenging environments like those found in automotive, aerospace, and industrial applications.

In addition, these alloys are employed in overcurrent protection devices and current-limiting components, where their temperature-responsive resistance helps safeguard circuits by automatically adjusting current flow at high temperatures. They are also used in battery management systems to maintain safe operating temperatures. The thermal stability, corrosion resistance, and self-regulating properties of these Ni-Fe alloys make them adaptable and valuable materials for applications that demand reliable thermal control and protection.

Some key features of NF36 include:

1. Low Coercive Field:
This alloy can achieve a very low coercive field (2 A/m), which is beneficial for high precision torque sensors.
2. Magnetic Properties:
The addition of copper or chromium & titanium can effectively reduce the remanence and the coercive field of the Fe50Ni50 alloy.
3. Curie Point Tunability:
The alloy's Curie point and Hopkinson peak can be tuned, which is driving new non-contact temperature sensing technology.
4. Austenitic Structure:
When austenitic, these alloys exhibit great plasticity and very soft magnetic material behavior with respect to magnetic anisotropy energies.
5. Saturation Polarization:
They are characterized by a medium amplitude of saturation polarization (0.3 < Jsat ≤ 1.5 T) at room temperature and a low Curie point (20 < Tc < 450 °C).
6. Industrial Applications:
Traditional uses include components for transformers, synchro-resolvers, miniaturized motors, high-sensitivity relays, low-frequency inductors, and open-loop current sensors.
7. Market Growth:
The Fe50Ni50 market is expected to grow, thanks to applications in torque sensors, gas safety actuators, temperature-controlled induction heating, and additive manufacturing of actuator parts.
8. Metallurgical Solutions:
There are metallurgical solutions to trigger anomalous grain growth, allowing for the achievement of a coercive field less than 1.5–2 A/m, which can further improve torque sensor accuracy.
9. Magnetic Annealing:
Magnetic annealing of wound cores can induce anisotropy, which lowers the magnitudes of remanence and permeability.
10. Additive Manufacturing:
The alloy's properties make it suitable for additive manufacturing processes, which can produce complex geometries without the need for post-process heat treatment.
These features highlight the versatility and adaptability of PTC Ni-Fe alloy Ni-50-55 in meeting the demands of precision and performance in a variety of technological applications.

Applications:

  • Temperature Sensors
  • Thermistors
  • Self-Regulating Heating Elements
  • Overcurrent Protection Devices
  • Battery Management Systems
  • Current Limiting Devices

These applications take advantage of the alloy’s PTC behavior, thermal stability, and corrosion resistance, making it suitable for various industries where reliable thermal regulation and protection are essential.
